Section 13 Bus State Controller (BSC)
Read-Strobe Negate Timing (Setting Only Possible in the SH7750R): When the SRAM
interface is used, timing for the negation of the strobe during read operations can be specified by
the setting of the A1RDH and A4RDH bits of the WCR3 register. For information about this
setting, see the description of the WCR3 register. When a byte control SRAM setting is made,
AnRDH should be cleared to 0.
